Issue with theme installation on Drupal 9

Hi @SeaserWeb, @Vishal Choudhary, @arti_parmar, @Ashutosh Ahirwal

I have created MR!34 for the above issue please review it once.

Thank you !!

Hi akhil_01,
I installed the theme using this command composer require 'drupal/ajans:^6.0' and did not got this error.
Did you use this composer require 'drupal/ajans:^1.0' for installing in drupal 9 for 10 instance.
